Domain structure and domain-domain interactions of recombinant tissue plasminogen activator.
The melting of recombinant tissue plasminogen activator (rtPA) has been investigated by differential scanning calorimetry and fluorescence spectroscopy. At neutral pH, rtPA melts with only partial reversibility in a single sharp peak that can be deconvoluted into four transitions. By contrast, at acidic pH the melting process is spread over a broad range of temperature and is highly reversible....
متن کاملStructure, function and antagonists of urokinase-type plasminogen activator.
Urokinase (uPA) is a serine protease which converts plasminogen to plasmin, a broad-spectrum protease active on extracellular matrix (ECM) components. Like many components of the blood coagulation, fibrinolytic and complement cascades, uPA has a modular structure, including three conserved domains: a growth factor-like domain (GFD, residues 1 - 49), a kringle domain (residues 50 - 131), linked ...
متن کاملThe structure of the urokinase-type plasminogen activator receptor gene.
The cellular receptor for urokinase-type plasminogen activator (uPAR) is a glycosylphosphatidylinositol (GPI)-anchored membrane protein that plays a central role in pericellular plasminogen activation. It contains 313 amino acid residues, including 28 cysteine residues in a pattern of three homologous repeats. The cysteine residue pattern suggests that uPAR belongs to a superfamily of proteins ...
متن کاملCombination of Single-Chain Urokinase-Type Plasminogen Activator and Recombinant Tissue-Type Plasminogen Activator in Acute Myocardial Infarction
The effects of simultaneous intravenous infusions of 12 mg recombinant tissue-type plasminogen activator (rt-PA) over 30 minutes and 48 mg single-chain urokinase-type plasminogen activator (scuPA) over 40 minutes were studied in 38 patients with acute myocardial infarction. Coronary arterial patency was assessed angiographically 60 minutes and 90 minutes after initiation of treatment. Patency w...
متن کاملUrokinase-type plasminogen activator promotes paracellular transmigration of neutrophils via Mac-1, but independently of urokinase-type plasminogen activator receptor.
BACKGROUND Urokinase-type plasminogen activator (uPA) has recently been implicated in the pathogenesis of ischemia-reperfusion (I/R) injury. The underlying mechanisms remain largely unclear. METHODS AND RESULTS Using in vivo microscopy on the mouse cremaster muscle, I/R-elicited firm adherence and transmigration of neutrophils were found to be significantly diminished in uPA-deficient mice an...
